Mechman high output alternators · Authorized dealer
A GS350 often racks up long commuting miles, and owners who replace the factory audio with amplifiers and a processor want that system to perform the same on every drive. A Lexus GS350 high output alternator adds charging capacity to the 3.5L V6. The Mechman units here cover 2007-2015 models in 320 Amp and 240 Amp outputs.
Mid-size sport sedans spend hours on the highway, frequently with headlights, climate control, heated or cooled seats and a phone mount charger running together. Add an aftermarket amplifier array and a subwoofer, and the charging system works harder than it did when the car was new. A Lexus GS350 high output alternator supplies the margin to run the cabin comforts and the stereo at full strength through rush hour traffic.
Two Mechman high output alternators are listed for the 2007-2015 GS350 with the 3.5L V6. The 240 Amp unit suits a moderate system with one or two amplifiers. The 320 Amp unit is the stronger choice for multi-amp builds or added lighting. Check your model year and engine in the vehicle finder above the products before you buy.
The same series fits the Lexus IS350 and Lexus IS250. A replacement battery is worth considering on a higher-mileage car, and the Lexus alternators page covers the rest of the lineup.
